在Fedora上安装MySQL gem的问题

Question

当我尝试rake db:migrate时,我收到以下错误:

The bundled mysql.rb driver has been removed from Rails 2.2.
Please install the mysql gem and try again: gem install mysql.
rake aborted! no such file to load -- mysql

当我尝试时 gem install mysql

Building native extensions. This could take a while... ERROR: Error installing
mysql: ERROR: Failed to build gem native extension. /usr/bin/ruby extconf.rb
Can't find header files for ruby. Gem files will remain installed in
/usr/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.

$ sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

也尝试了但同样的错误.我在Fedora 10上.非常感谢帮助.欢呼!

Answer 1

在安装MySQL gem之前,您需要安装Ruby和MySQL的Fedora开发包.尝试:

$ sudo yum -y install gcc mysql-devel ruby-devel rubygems

然后重试你的:

$ sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

(还要检查/ usr/local/mysql/bin是mysql_config的正确位置,它可能是/ usr/bin.)
